Tess, I hope you are getting some much needed space 
I think this thread is so insightful. The whole subject of what the best 'solution', if there can be one, is one thing. That is very emotive and it is quite humbling reading posters' experiences on both sides of the fence.
The other big subject of sexual education and responsibility seems just HUGE. I don't know quite what to think. I certainly wouldn't want my 13/14/15/16 year old DDs to be having sex, and I would hope that they would be in a stable relationship before doing so, but balancing that and giving them the means to be safe whilst encouraging responsibility -what are the options? I mean providing contraception sounds so sensible, yet in its own way somehow condoning and almost encouraging.
It does make me think that no matter what my personal hopes for my children, it is essential that sex education is seen as natural and important to talk about from an early age as, say, personal hygiene.
To read a thread like this is incredible, alongside threads which say 'my 12 year old asked what a condom was, and I didn't know what to say
'. Where is the middle ground?
